A comparison of methods for the measurement of the absorption coefficient in natural waters

Creator:: Pegau, W. Scott, Cleveland, Joan S., Doss, W., Kennedy, C. Dan, Maffione, Robert A., Mueller, James L., Stone, R., Trees, Charles C., Weidermann, Alan D., Wells, Willard H., and Zaneveld, J. Ronald
Abstract:: In the spring of 1992 an optical closure experiment was conducted at Lake Pend Oreille, Idaho. A primary objective of the experiment was to compare techniques for the measurement of the spectral absorption coefficient and other inherent optical properties of natural waters. Daily averages of absorption coefficients measured using six...

Microstructure activity within a minifilament in the Coastal Transition Zone

Creator:: Dewey, Richard K., Moum, James N., and Caldwell, Douglas R.
Abstract:: This paper presents observations of a dynamic minifilament and summarizes the findings of three microstructure surveys across and within the meandering current structures of the Coastal Transition Zone (CTZ). An actively turbulent minifilament is discussed and possible consequences of the small-scale processes with regard to frontal dynamics are examined. Four...

Geochemistry of back arc basin volcanism in Bransfield Strait, Antarctica: Subducted contributions and along-axis variations

Creator:: Keller, Randall A., Fisk, Martin R., Smellie, John L., Strelin, Jorge A., and Lawver, Lawrence A.
Abstract:: Bransfield Strait is a Quaternary, ensialic back arc basin at the transition from rifting to spreading. Fresh volcanic rocks occur on numerous submarine features distributed along the rift axis, including a discontinuous neovolcanic ridge similar to the nascent spreading centers seen in some other back arc basins. Smaller edifices near...

Introduction to special section on Recent Advances in the Study of Optical Variability in the Near-Surface and Upper Ocean

Creator:: Dickey, T., Banner, M. L., Bhandari, P., Boyd, Timothy John, 1958-2013, Carvalho, L., Chang, G., Chao, Y., Czerski, H., Darecki, M., Dong, C., Farmer, D., Freeman, S., Gemmrich, J., Gernez, P., Hall-Patch, N., Holt, B., Jiang, S., Jones, C., Kattawar, G., LeBel, D., Lenain, L., Lewis, M., Liu, Y., Logan, L., Manov, D., Melville, W.

K. P., Zaneveld, R., and Zappa, C. J.
Abstract:: Optical variability occurs in the near-surface and upper ocean on very short time and space scales (e.g., milliseconds and millimeters and less) as well as greater scales. This variability is caused by solar, meteorological, and other physical forcing as well as biological and chemical processes that affect optical properties and...

Short-wavelength instabilities on coastal jets and fronts

Creator:: Barth, John A.
Abstract:: The stability of a coastal jet and front is investigated using the primitive equations applied to a continuously stratified flow in geostrophic balance. A linear stability analysis successfully explains the growth of two modes of instability with distinctly different horizontal scales. A long-wavelength mode (fastest-growing wavelength of 0(100 km)) is...

Direct radiative effect of mineral dust and volcanic aerosols in a simple aerosol climate model

Creator:: Shell, Karen M. and Somerville, Richard C. J.
Abstract:: Airborne mineral dust can influence the climate by altering the radiative properties of the atmosphere, but the magnitude of the effect is uncertain. An idealized global model is developed to study the dust-climate system. The model determines the dust longwave and shortwave direct radiative forcing, as well as the resulting...

In situ cosmogenic radiocarbon production and 2-D ice flow line modeling for an Antarctic blue ice area

Creator:: Buizert, Christo, Petrenko, Vasilii V., Kavanaugh, Jeffrey L., Cuffey, Kurt M., Lifton, Nathaniel A., Brook, Edward J., and Severinghaus, Jeffrey P.
Abstract:: Radiocarbon measurements at ice margin sites and blue ice areas can potentially be used for ice dating, ablation rate estimates and paleoclimatic reconstructions. Part of the measured signal comes from in situ cosmogenic ¹⁴C production in ice, and this component must be well understood before useful information can be extracted...

Sensitivity of climate forcing and response to dust optical properties in an idealized model

Creator:: Shell, Karen M. and Somerville, Richard C. J.
Abstract:: An idealized global climate model is used to explore the response of the climate to a wide range of dust radiative properties and dust layer heights. The top-of-the-atmosphere (TOA) shortwave forcing becomes more negative as the broadband shortwave single scattering albedo increases and the broadband shortwave asymmetry parameter decreases, but...

Generation of edge waves in shallow water

Creator:: Lippmann, T. C., Holman, Robert A., and Bowen, A. J.
Abstract:: Theoretical growth rates for resonantly driven edge waves in the nearshore are estimated from the forced, shallow water equations of motion for the case of a plane sloping bed. The forcing mechanism arises from spatial and temporal variations in radiation stress gradients induced by a modulating incident wave field. Only...

Vertical velocity, vertical diffusion, and dilution by midlatitude air in the tropical lower stratosphere

Creator:: Mote, Philip W., Dunkerton, Timothy J., McIntyre, Michael E., Ray, Eric A., Haynes, Peter H., and Russell, James M.
Abstract:: Air passing upward through the tropical tropopause is “marked” by an annually varying water vapor mixing ratio much as a tape recorder marks a magnetic tape; as the air ascends in the tropical stratosphere, these marks are effaced by a combination of vertical diffusion within the tropics and dilution of...
